Morphing wings, intended as wings capable of changing their geometry based on unconventional methods, such as compliant structures and so-called smart materials represent a very active area of research as they promise to allow for superior performance under a wide range of conditions, as compared to conventional wings. In most cases, morphing wing designs are faced with a fundamental conflict in the design: While high stiffness levels are desirable from a structural point of view, morphing of stiff structures requires large forces and thus heavy actuators and considerable amounts of energy. The concept of Electro-Bonded Laminates (EBL) presented here overcomes this classical requirements' conflict. In this technique, thermoplastic films are embedded within electrically conductive material. A reversible lamination is achieved by applying electrostatic forces. The shear strength of these materials can be controlled by the voltage applied. The required current for maintaining the lamination is limited to creep currents, which are present in the insulating thermoplastic layers. Applications of the approach to a small-scale section of a morphing wing are shown.
